Chahine, M. T., 1993, "Observation of Local Cloud and Moisture Feedbacks Associated with High Ocean and Desert Surface Temperatures", https://hdl.handle.net/2014/34988, n/a, JPL Open Repository
New data on clouds and moisture, made possible by reanalysis of weather satellite observations, show that the atmosphere reacts to warm ocean pools in the Western Pacific Ocean with increased moisture and cloudiness, suggesting a negative feedback limiting the rise in sea-surface... |

Israelsson, U. E.; Duncan, R. V., 1993, "Design of a Low Gravity Simulator for Performing Non-Equilibrium Investigations near the Lambda Transition of ^4He", https://hdl.handle.net/2014/35381, ['Bulletin of the American Physical Society', 'Seattle, Washington'], JPL Open Repository
A design is presented of a low gravity simulator where a magnetic field gradient is employed to oppose the hydrostatic pressure effects of gravity. It appears feasible to reduce the effective gravity environment of the helium in the cell by about two orders of magnitude. The corr... |

Krabach, T.N.; Staller, C.; Dejewski, S.; Cunningham, T.; Herring, M.; Fossum, E.R., 1993, "InGaAs Detectors for Miniature Infrared Instruments", https://hdl.handle.net/2014/34839, ['SPIE: Infrared Systems Engineering', 'Los Angeles, CA'], JPL Open Repository
In the past year, there has been substantial impetus for NASA to consider missions that are of relatively low cost as a trade off for a higher new mission launch rate. To maintain low mission cost, these missions will be of short duration and will use smaller launch vehicles (e.g... |

Toth, R. A., 1993, "The v1-v2, v3-v2, v1, and v3 bands of H216O: line positions and strengths", https://hdl.handle.net/2014/34957, UNKNOWN, JPL Open Repository
High-resolution spectra of H216O were recorded with a Fourier-transform spectrometer covering transitions in the (100)-(010), (001)-(010), (100)-(000), and (001)-(000) bands. The measured line frequencies were used to determine high accuracy values of rotational energy levels in... |

Schwuttke, U.M.; Gasser, L., 1993, "Improving Real-time Performance of Intelligent Systems with Dynamic Trade-off Evaluation", https://hdl.handle.net/2014/36342, USA, JPL Open Repository
This paper describes dynamic trade-off evalation (DTE), a new technique that has been developed to improve the performance of real-time problem solving systems. The DTE technique is most suitable for environments in which the requirement for meeting time constraints is of equal o... |
